Microphthalmia, Lenz Syndrome

Lenz Microphthalmia Syndrome (LMS) can be highly variable in its phenotypic presentation between families and even between members of the same family. The eyes are usually asymmetrically affected with ocular anomalies, such as microphthalmia/anophthalmia, coloboma and cataract. Mild-moderate mental retardation and urogenital anomalies (hypospadias, cryptorchidism, renal aplasia/hypoplasia, hydroureter) are the most common associated findings. Hearing loss has also been reported.
